Celestia is a free real-time space simulation that lets you experience our
universe in three dimensions. Unlike most planetarium software, Celestia
doesn't confine you to the surface of the Earth. You can travel throughout
the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All travel in Celestia is seamless; the exponential zoom feature lets you
explore space across a huge range of scales, from galaxy clusters down to
spacecraft only a few meters across. A "point-and-goto" interface makes it
simple to navigate through the universe to the object you want to visit.
Celestia is expandable. It comes with large catalog of stars, galaxies,
planets, moons, asteroids, comets, and spacecraft. If that's not enough,
you can download dozens of easy to install add-ons with more objects.
GPS::OID maps GPS PRN number to Satellite OID and vice versa.
FoxtrotGPS is a fork of Marcus Bauer's TangoGPS project, with a focus on
cooperation and fostering community innovation. It is a lightweight moving
map application that can be used with or without a gps unit. By default,
maps tiles are downloaded from the OpenStreetMap project, but other sources
are available, and new ones may be added.
Map areas may be downloaded and cached for use while offline.
These drivers are for using certain Garmin GPS units with QLandkarteGT.
Supported devices are:
- Etrex Legend series (C, Cx, HCx, ...)
- Etrex Summit HC
- Etrex Venture Cx, HC
- Etrex Vista series (C, Cx, HCx)
- Forerunner 305
- GPSMap60 series (C, CS, CSx, Cx)
- GPSMap76 seriex (CS, CSx, Cx, S)
- Quest
- Rino 120
GeographicLib is a small set of C++ classes for performing conversions
between geographic, UTM, UPS, MGRS, geocentric, and local cartesian
coordinates, for gravity (e.g., EGM2008), geoid height, and geomagnetic
field (e.g., WMM2010) calculations, and for solving geodesic problems.
The library may be used from .NET applications using the NETGeographicLib
wrapper library. It is a suitable replacement for the core functionality
provided by geotrans.
gkrellmoon is a moon clock plugin for Gkrellm2. This plugin is based
upon the glunarclock and wmMoonClock applications.
The port is based on the original gkrellmoon port for Grellm1 by Patrick Li.
This is a Perl module that gives access to several GPS protocols, such as
Garmin, NMEA, and Magellan. It works in Unix and Win32.
Viking is a free/open source program to manage GPS data.
You can import and plot tracks, routes and waypoints, show OpenStreetMap,
Terraserver, Bing Aerial and other maps in it, download geocaches for
an area on the map, make new tracks and waypoints, geotag images,
see real-time GPS position, etc.
